Question

how to find energy of photon of first line of Lyman series​

Answer 1

Answer:

Calculate the masses of photons corresponding to the first lines of Lyman and Balmer series of the atomic spectrum of hydrogen are in the ratio.

Explanation:

Since energy is directly proportional to mass and mass is inversely proportional to wavelength (

λ=

mv

h

Deleroglie's wavelength Equation)
